110V Operation
SECTION 2: CIRCUIT REQUIREMENTS
A 15-amp fuse or circuit breaker should be used
when connecting this Bench Grinder. Circuits
rated any higher are not adequate to protect the
motor from power surges.
Equipment returned to us for service that shows
evidence of being over-fused will be repaired or
replaced totally at the customer’s expense,
regardless of the present warranty status.
Fusing
If you find it necessary to use an extension cord
with the Model G8220, make sure the cord is
rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin. Always repair or
replace extension cords when they become worn
or damaged.
Extension Cords
Grounding
This equipment must be grounded. Verify
that any existing electrical outlet and circuit
you intend to plug into is actually ground-
ed. If it is not, it will be necessary to run a
separate 12 A.W.G. copper grounding wire
from the outlet to a known ground. Under
no circumstances should the grounding pin
from any three-pronged plug be removed.
Serious injury may occur.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent. This tool is equipped with a power cord hav-
ing an equipment-grounding conductor. See
Figure 1. The outlet must be properly installed
and grounded in accordance with all local codes
and ordinances.
The Model G8220 is wired for 110V, single phase
operation only. The 1⁄4 HP motor will draw 1 amp
at 110V. If you operate this grinder on any circuit
that is already close to its capacity, it might blow
a fuse or trip a circuit breaker. However, if an
unusual load does not exist and a power failure
still occurs, contact a qualified electrician or our
service department.

Site Considerations Notes
BENCH MOUNTING
Your G8220 Wet/Dry Grinder is designed to be
used on a workbench. Make sure it is positioned
at a comfortable working height. The machine
can be permanently mounted to a bench by
removing the base and using the four holes in the
motor body to secure it directly to the surface of
a bench.
WORKING CLEARANCES
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without
limitation. Ensure that your working area offers
plenty of room for free movement and a substan-
tial amount of distance between you and others
that may be working in your shop space.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or exten-
sion cords are not obstructing high-traffic areas.
Be sure to observe local electrical codes for prop-
er installation of new lighting, outlets, or circuits.
Make your shop “child safe”. Ensure that
your workplace is inaccessible to young-
sters by closing and locking all entrances
when you are away. Never allow visitors in
your shop when assembling, adjusting or
operating equipment.

SECTION 4: ASSEMBLY
Tool Rest/Eye Shield
To assemble the Eye Shield:
1.Take the L-shaped bracket and position it
so the holes line up and the bracket is on
the underside of the plastic shield.
2. Use the two (2) combination head screws,
washers and nuts to secure the L-bracket
in place.
3. Attach the assembled Eye Shield to the
right side of the wheel guard using the
short hex head bolt and washer.
Water Reservoir
Insert the water valve into the hole in the Water
Reservoir. Attach the Water Reservoir to the
post behind the wet grinding wheel. Position the
water drip over the center of the grinding surface.
Attach the clear plastic drain pipe to the fitting
which in on the underside of the wet wheel hous-
ing.

Tool Rest-Wet Wheel
The large horizontally mounted wet grinding
wheel also has a tool rest situated over it to aid
the user in the grinding operations:
1. Position the two support brackets in the
wide grooves which are located on each
side of the water tray. The recess in the
shape of a half circle should be facing out-
ward on each side. See Figure 4.
Figure 4. Mounting rest holder.
Figure 5. Mounting tool rest.
2. Thread a locking knob with washer through
the hole in the bottom of the holder and into
the water tray body. These knobs control
the overall height of the tool rest assembly.
3. Set the tool rest into the half circle recess-
es. The sliding tool rest should already be
assembled onto the holder, if it is not, slide
the tool rest into the groove. It only goes
one way as there is a tab preventing incor-
rect installation. The miter gauge also
should already be positioned on the sliding
tool rest.
4. Attach the tool rest assembly to the support
brackets. Using the M4-.7 x 30mm Hex
Head Bolt, push the bolt through from the
inside of the holder and secure a knob to it
on the outside. See Figure 5. These two
knobs control the angular adjustment of the
tool rest. The hex heads will lock into a
recess molded into the inside of the brack-
et.

SECTION 5: Operations
The dry wheel supplied with the G8220 is an 80
grit Aluminum Oxide wheel good for heavy mate-
rial removal and for roughing in to approximate
dimensions. The wet wheel is a very fine 1000
grit which, along with the water supply, allows
fine grinding and honing to very precise edges.
Choose the wheel and grinding method appro-
priate for your grinding needs.
naturally generated during the grinding process.
Secondly, the water acts as a lubricant for the
grinding process improving the cutting character-
istics of the fine grit wheel. As you begin grinding,
adjust the water flow so there is a steady drip
onto the surface of the wheel, close to the inner
edge. Make sure the drain pipe coming out the
underside of the water tray is directed so it is
going into some type of container.
Plug the machine in and turn the motor on. Allow
the wheel to get up to full operating speed before
beginning the grind. Introduce the item to the
wheel slowly and carefully, making sure it is fully
supported against the tool rest and miter gauge.
For some types of grinds, it may be necessary to
sweep the item across the wheel surface by slid-
ing the tool rest across the holder. Always lift the
item off the surface when returning to the starting
point of the sweep. Do not let the workpiece get
too hot during grinding. If heat is increasing, slow
down the rate of grind, or turn up the water flow.
High heat will destroy the temper of the metal
and will make it impossible to hold an edge.
Use extreme caution when sharpening any
type of knife, both during and after sharp-
ening. Make certain the knife is fully sup-
ported by the rest before bringing it into
contact with the wheel. Failure to exercise
care while working near knives could result
in severe injury.
Overview
Wet Wheel Grinding
There are three adjustments necessary to get the
proper grinding angle. Tool rest height, tool rest
angle, and miter gauge angle must all be adjust-
ed to get the proper angle of attack on the grind-
ing wheel. Be sure the machine is off and
unplugged. Lay the item to be ground on the rest
and lay it against the stationary wheel. Adjust all
three elements until the blade contacts the wheel
in the proper orientation. A typical set up for a
bevel tip chisel is shown in Figure 6.
The water reservoir allows the operator to drip
water onto the wheel during the grinding process.
The water serves two purposes. One is to provide
a certain amount of cooling for the heat which is
Figure 6. Typical wet wheel grinding operation.

-12- G8220 Wet/Dry Bench Grinder
Long straight types of blades such as jointer or
planer knives can also be sharpened on this
machine as well. Position the blades as shown in
Figure 7, with the miter gauge set at a zero
angle. For this type of operation, it is necessary
to sweep the blade edge across the wheel. The
sliding table retained in the groove of the tool
rest holder allows for this sweeping action. Allow
the blade edge to push the circular foam materi-
al down, this is perfectly acceptable and helps to
insure the water does not spin off the wheel.
Maintain a constant and steady pressure
throughout the entire range of the sweeping
action to ensure that the blade is evenly ground
all the way to its edges. Be sure to avoid over-
heating the blades during grinding.
Figure 7. Grinding long knives.
Figure 8. Grinding on dry wheel.
Adjust the angle of the Tool Rest by loosening
the two lock knobs. The angle can also be affect-
ed by raising or lowering the entire Tool Rest
assembly by loosening the hex bolt at the front of
the wheel guard. Once you have achieved the
angle necessary for the item to be ground, make
certain all the adjustment knobs and bolts are
tightened so the rest will not move during grind-
ing.
Position the Eye Shield so it will cover the grind-
ing area. The Eye Shield can be moved up and
down, as well as back and forth, to get it in a
position where sparks will not fly up in the oper-
ator’s face. Tighten the adjusting bolt.
For dry grinding, it may be helpful to have a tray
of water handy for quenching the piece when it
builds up heat in the grinding process. Similar to
the wet wheel process, quenching keeps the
ground item from losing its temper by keeping
the temperature down.
Turn the grinder on and allow the wheel to come
up to full speed. Place the item to be ground
firmly on the Tool Rest and introduce it slowly
into the wheel. Grinding should be done lightly
and for short duration to avoid damage to the
tool you’re working with.
Use extreme caution when working near
rotating grinding wheels. Accidental con-
tact with the wheel can cause cuts and
abrasions. The spinning wheels can also
propel items which are not firmly support-
ed. Failure to exercise care while working
near grinding wheels could result in severe
injury.
